2. New Apple Mail
The new features included in the Apple mail come out of all the traditional mail features. For example, the new mail feature allows large files to be attached and send for free. Previously, you could only attach upto 10mb of files where now it extends up to a massive 5GB. This means you can send high resolution images and even HD videos with utter convenience and ease. Apple calls this new feature Mail Drop where through the use of iCloud uploads, sending big files is much faster and easier than ever before.
